Picture of Tinea Capitis
Tinea capitis is also known as ringworm of the scalp. This fungal infection generally affects school-age children and may spread in schools. It appears as scalp scaling associated with bald spots usually showing broken-off hairs. Oral antibiotics are needed to penetrate the hair roots and cure the infection after which hair grows back.
